Once one of them started gaming the tests and nobody reported it, it's not unreasonable to assume others started doing it too. There are real costs to complying. VW has been kicking everybody's tail in diesel too, so I'd expect one of two things after they all had a chance to reverse engineer tdi, they'd buy VW motors for their cars or they'd do the same tricks. It will be interesting to see unfold, it could very well end diesel in consumer cars which would be unfortunate as I think there are real values to the diesel cycle.
